Different Types of ComputerHardware
INTERNAL HARDWARE
MOTHERBOARD
the motherboard is a central printed circuit board (PCB) that connects various components directly or indirectly.
It is the backbone of the computer system
It enables electrical and logical channels for communication and data transfer between the CPU, RAM, storage devices, expansion cards, and other computer hardware components
different types of mother board :
ATX -This is the most popular and widely used form factor for desktop PCs
An Extended-ATX (E-ATX) motherboard is a type of motherboard with a larger size and more slots than a standard ATX motherboard
Mini ITX -This is the smallest standard form factor for desktop PCs
Micro ATX-This is a smaller version of the ATX form. It can still support most of the same components as an ATX motherboard, but with less room.
BTX- A BTX motherboard is a type of computer motherboard that follows the Balanced Technology Extended (BTX) standard
LPX -An LPX motherboard is a type of computer motherboard with a low-profile design and a smaller form factor than the standard ATX motherboard. :
[RAM
RAM (Random Access Memory) is computer
hardware
that stores and processes information. The processing speed of RAM is much faster than a hard disk
RAM is a volatile device, meaning all stored information gets deleted when a computer system shuts down.
The data is easily stored and fetched from RAM. The data fetching process is very fast in RAM compared to hard disk.
2 TYPES OF RAM
DRAM (Dynamic Random Access Memory) is used mostly in modern computers.
The use SRAM (Static Random Access Memory) is in the cache memory of the CPU
HARD DISK
The hard disk is the non-volatile component, which means the data is stored permanently in the hard disk and does not wipe out when the system is shut down.
The internal hard disk has a collection of stacked disks with electromagnetic surfaces that stores huge chunks of data and can be accessed easily.
The hard disk is another internal computer hardware used to store data. It can be preinstalled in the CPU or used as an external device.
The hard disk can store trillions of bytes of data in its system. Every hard disk has a certain processing speed ranging from 4200-15000 rpm.
SSD
A solid-state drive (SSD) is a computer data storage device based on semiconductors.
This non-volatile storage device depends on flash-based memory, NAND, and NOR to store and retrieve data electronically.
SSDs perform the same function as traditional hard disk drives (HDD) in computers
SSDs are a popular choice for laptops, desktops, servers, and other devices because they offer faster read/write speeds, lower power consumption, and higher durability than HDDs.
DIFFERENT TYPES OF SSD
SATA SSD
This is the most common SSD type and should be compatible with the widest range of PCs, even old ones.
NVMe ( Non-Volatile Memory Express )can achieve industry-leading storage performance while remaining extremely compact and straightforward to install.
M.2, has become the standard type of storage for slim laptops and notebooks. Its tiny form factor is often compared to a stick of gum and easy to install right on the motherboard in most cases.
A PCIe SSD (Peripheral Component Interconnect Express solid-state drive) is a high-speed expansion card that attaches a computer to its peripherals.
CPU (Central Processing Unit) is the core hardware of the computer system, which interprets and executes most of the commands using other computer parts.
The CPU is also a core part of laptops, tablets, and notebooks. The CPU, also known as the computer’s brain, executes every operation of the computer system.
It comprises a computer chip with billions of small transistors installed on the CPU. These transistors perform all the calculations of the computer system.
The other hardware components, including the monitor, keyboard, mouse, printer, and sound system, are connected to the CPU
EXTERNAL HARDWARE
MONITOR
The monitor is another computing device directly connected to the CPU that displays the output, videos, and other graphics.
The video shown by the monitor uses the video card. The monitor screen is comparable to the screen of a TV. But the difference lies in the resolution and graphics.
The monitor displays high-quality resolution compared to the TV screen. It is connected via a cable and mounted in a video card installed in the computer system’s motherboard
The monitor is pre-built in the system for laptops and tablets, and no separate hardware is required for these devices
2 TYPES OF COMPUTER MONITOR
The CRT(Cathode Ray Tube)is an old model of computer.
LCD monitor (Liquid crystal display)is the most widely used monitor in the world. It tends to take up less space, less electricity, generate less heat, and are thinner and lighter than the ageing CRT monitors. The USP of these monitors is the bright screen, and their cost-effectiveness.
MOUSE
A mouse is a hand operator input device to point out something on the screen.
The mouse can be wired or wireless. A wired mouse is connected directly to the CPU
The cursor on the screen will move directly under the command/movement of the mouse.
The mouse has a laser/scroll ball to scroll up or down on the screen
DIFFERENT TYPES OF MOUSE
Wired Mouse
A wired mouse connects directly to your desktop or laptop, usually through a USB port, and transmits information via the cord.
Wireless Mouse
Wireless mice transmit radio signals to a receiver connected
to your computer. The computer accepts the signal and decodes how the cursor was moved or what buttons were clicked
Bluetooth Mouse
Wireless mouse designs and Bluetooth mouse designs tend to look very similar, as neither need a wired connection to operate.
Gaming Mouse
This type of mouse is specially built to give you a premium gaming experience and you can easily pair it with other gaming setup accessories. A gaming mouse has a button on the right side which you can choose to customize. Besides the button, it is also designed with a DPI button.
KEYBOARD
The keyboard is another computer hardware used to give input text and commands to the computer. It can be wired or wireless.
The keyboard contains numbers, alphabets, special characters (#,*,&,%), and other buttons to give input to the computer.
This device takes input/information from the user and processes the commands.
DIFFERENT TYPES OF KEYBOARD
Wired Keyboards
Wired keyboards offer an affordable and effortless swap if you want to find a keyboard style that suits your needs.
Ergonomic Keyboards
Ergonomic keyboards refer to any keyboards designed to reduce strain on the body from typing. These kinds of keyboards are often laid out so that you can rest your hands in a more comfortable, natural position as you type
Wireless Keyboards
Relying on a radio frequency antenna or infrared to keep you connected, wireless RF keyboards offer a bit of freedom in your computing activities.
USB Keyboards
This variety of wireless keyboard connects to your PC using a small device called a dongle, which you plug into one of your laptop’s USB ports. The dongle transmits a signal between your laptop and the keyboard to enable wireless typing.
Magic Keyboards
Offered by Apple, the Magic Keyboard brings a polished look and rechargeable battery to the table. These Bluetooth-enabled keyboards connect to Mac computers automatically. As with any other Apple product, however, the “Magic” comes at a price; these are some of the most expensive everyday keyboards on the market.
Membrane Keyboards are often covered by transparent and plastic shell which is mostly use in medical facilities. It can also be used in mobile or landline phones.
Numeric Keypads
Not all computers come with keyboards that include the number pad. The numeric keyboard is an easy solution for that
Apple Macintosh Keyboards also called ADB keyboard as it connects to the Apple desktop bus and comes with two varieties in standard and extended which features 15 extra function keys.
PRINTER
A Printer is a computer hardware output device that produces hard copies of contents, digital documents, or images on paper or other media.
it takes electronic data from a computer system and transforms it into a printed image or text.
VARIOUS TYPES OF PRINTER
Inkjet printers- are the de-facto standard for consumer/home-use printers. They’re inexpensive and use liquid ink that is relatively inexpensive to replace. They can produce high-quality color printing or fairly fast monochrome (aka B&W) prints. Inkjet printers are good if you only print occasionally, or don’t need the highest-quality printings.
Dot Matrix Printers
The oldest of old-school computer printers, dot matrix printers use a pin or wire print head to press an ink ribbon against a piece of paper. If you remember the reams of paper with tear-off perforated holes on the side, that’s a dot matrix printer.
3D Printers
The technology behind 3D printers can get pretty complicated, but it’s one that’s become incredibly popular with DIYers and hobbyists looking to go hands-on with their own creations. Essentially, they use layering and slicing to produce 3D objects, typically in plastic, based on digital models created in your choice of software.
Laser Printers
Laser printers, as their name suggests, use a laser beam to heat a toner material that embeds itself onto the paper. Most business-oriented models are monochrome, but there are color laser printers as well. Toner cartridges are typically more expensive than ink, but also usually last longer.
SPEAKER
A speaker is an essential external audio output computer device. It produces audio output for listening to music, watching videos, playing games, and conducting video conferences.
The computer sends audio signals to speakers, which are then converted into sound waves that the users can hear
Speakers are connected to the computer’s audio output port, usually a USB port.
They come in various sizes, shapes, and designs, with features such as wireless connectivity, voice control, and built-in microphones.
TYPES OF COMPUTER SPEAKER
5.1 speaker is a type of computer speakers is considered to be most one of the most suitable sound setups. In addition, the 5.1 speakers provide a multi-channel output and a surround sound system which proves to be very effective for video games and movies etc
7.1 -The 7.1 speakers system is one of complex types of computer speakers and contains 7 satellite speakers along with one subwoofer.
The cordless or wireless type of computer speakers has permitted the users to get rid of the mess of wires that are associated with the surround sound speaker setups.
2.0 speakers is also one of the common types of computer speakers used all around the world and doesn’t take much space.
3.1 speakers are considered to be very appropriate for common usage and the place occupied by these speakers is very less.
he USB speakers are the type of computer speakers that are powered from 5 volts and the amplifier powered by the USB draws power through a USB cable. In these type of speakers there is no need of any kind of AC power source or batteries.
The surround sound setups are the ones that make usage of multiple speakers in order to render directional effects of sound and enveloping audio
